[wmii] Is there a way to register a 'callback'?

Hi,

I wonder whether I can register a 'callback' function at some point, like
after a new application window created. What I want to do is auto resizing
the new created window to a suitable width(like 75% of screen width) and
move current focused window to right column after it created. Or is there
another way to achieve this?

Thanks,
Jan
